Question
The atomic radii in periodic table among elements from right to left
✓

Answer

b
Atomic radius decreases from left to right within a period. This is caused by the increase in the number of protons and electrons across a period. One proton has a greater effect than one electron; thus electrons are pulled towards the nucleus, resulting in a smaller radius.

The atomic radii in periodic table among elements from right to left increases.
